Article 38 Declaration of restricted zone
England and Wales
Without prejudice to paragraph (2) the National Assembly may, on confirmation by the Chief Veterinary Officer of the disease on premises in Great Britain, declare a restricted zone in such part of Wales and of such size as it considers necessary to prevent the spread of disease.
The National Assembly must declare a restricted zone in Wales if the Chief Veterinary Officer advises it that in his or her opinion disease has become extensive in Great Britain and the declaration of such a zone would prevent its spread.
A restricted zone must remain in effect until—
such date as may be stated in the declaration; or
it is removed by further declaration of the National Assembly.
Any premises which are partly inside and partly outside a restricted zone are deemed to be wholly inside that zone except premises which are also partly inside—
a temporary control zone; or
a supplementary movement control zone;
a protection zone;
a surveillance zone;
a vaccination zone;
a vaccination surveillance zone; or
a wild animal infected zone.
